Options > Boundaries

The Boundaries items define the default boundary options.

Private boundaries

Allow new boundaries to be private — When selected, PowerMill creates boundaries that can be made private. They are not private on creation, but as soon as they are attached to a toolpath, or stock model, they become private. When deselected, creates ordinary boundaries that can be used by many toolpaths and stock models. This option determines the default behaviour, but you can override this on boundary creation.

Display private boundaries in the explorer — When selected, PowerMill displays private boundaries in the boundaries branch of the Explorer as well as in the individual toolpath branch of the Explorer. When deselected, displays private boundaries only in the individual toolpath branch of the Explorer.

Note: Groups always display any private boundaries placed in them.

Automatically delete unused private boundaries — When selected, PowerMill automatically deletes unused private boundaries. For example, if you have a toolpath using a private boundary and then you edit the toolpath to use a different boundary, the original boundary is deleted.

Edit history

Allow new boundaries to apply the edit history on calculation — When selected, PowerMill automatically applies the edit history on calculation of the boundary. For more information see Boundary editing history.
